If paragliding is a foreshadowing for human exploration of the sky.

So this time the launch of the hot air balloon represents the real sense of human contact with the blue sky and white clouds.

A small step to success is a giant step in the process of civilization.

From this moment on, flying is no longer a fantasy of human beings for 10,000 years. became a reality.

Meaning is more important than practical.

This seemingly simple hot air balloon lift-off proves to the world that human beings can fly into the blue sky and be as chic as birds.

April 2, 10001 in the new calendar. Kyushu State, Qingdao County, Dongzhou, Laoshan County, Aeronautical Research Institute of the Department of Physics under the jurisdiction of the Kyushu Academy of Sciences. Liu Jinghong and Lin Xiufeng stepped into the sky for the first time.

The world's first flying machine appeared from Laoshan County and from the Kyushu Academy of Sciences.

Officially announced to the world, the aerospace age has arrived.

Height controllable, safe and controllable, can complete flat vertical take-off and landing. A flying machine in the true sense, the first flying machine in the history of the new calendar world, has finally appeared in front of the world.

Perhaps compared to the Wright brothers, who first entered the blue sky more than 10,000 years ago in ancient times. A hot air balloon is not the same as an airplane.

In other words, it is a completely different era and a completely different course of scientific history. The probability of the final fit of science in a step-by-step development is less than 1 percent.

10,000 years ago, the Wright brothers were the first in the world to ascend to heaven. Fly in an airplane of your own invention.

10,000 years later, Liu Jinghong and Lin Xiufeng were the first to go to the sky and ride in a hot air balloon they invented.

Different scientific and technological products, the same historical significance. Completely overturning the idea of flight for thousands of years of scientists, the appearance of hot air balloons will cause turmoil in this world.

In Laoshan County, Megumi Yanagisawa looked at his son, standing in the hanging basket and waving and laughing wildly below. muttered: "This time, my Liu family is completely recorded in history." ”

Below, the people and intellectuals of Laoshan County all looked up in amazement at the rising hot air balloon in the sky. Dancing.

"It's flying!"

"They succeeded."

"Kyushu Science and Technology Award, there is finally a flying aircraft in the true sense."

"But in my experience, the direction and speed of this hot air balloon should be uncontrollable, it should be floating in the wind. But it's also remarkable, they have at least completed the first step, taking off from the ground. ”

"It's great."

"It's an honor for me to witness this historic moment."

“……”

All the people of Yamato were silent. They probably understand that their country still has too many deficiencies compared to Kyushu.

The people of the white-robed country were silent.

The people of the Rakshasa Kingdom were silent.

All the foreigners were silent at this moment.

There are still too many deficiencies in my own country, and I envy Kyushu for having this group of people......

The guests watched the hot air balloon fluttering in the sky, watched the hot air balloon fly into the clouds, and slowly landed in the wilderness. Be rendered speechless.

After a long time, Lin Ke muttered: "If it is promoted on a large scale and armed with my Kyushu army, then who dares to violate Kyushu?" ”

Qian Mao sighed: "However, there are still too many imperfections. ”

"What's imperfect?"

"This hot air balloon can't move as it wishes. It can only flutter in the wind, and where it floats depends entirely on God's mood. If it can be perfected, it should be able to make all kinds of movements with the operation. ”

Lin Ke also sighed: "Alas, yes. If only it could go up to the sky and into the earth, move sideways left and right, forward and backward. Even if it's a little slower, it will eventually become a weapon for my Kyushu. ”

At this time, Lin Xiufeng, who landed from the wilderness and walked back, laughed: "Next, it is the second achievement of my Aviation Research Institute." ”

With the paving of the hot air balloon, everyone is even more eager to see the results of the Aviation Research Institute.

A moment later, Liu Jinghong brought a large iron can and held a balloon in his hand.

The crowd asked, "What is this?" ”

Liu Jinghong said: "Although the hot air balloon can prove the human dream of flying, it still has many imperfections. Its movement is uncontrollable. However, the second achievement of our aviation institute is an idea. ”

"What assumptions?"

"Airship Vision."

"Huh?"

"According to the theory, hot air balloons can be lifted into the air, completely dependent on the buoyancy inside the balloon," Liu said. However, because of its shape, it is not sealed, etc., so it cannot be moved. However, on the basis of the hot air balloon, we imagined that if we built a completely sealed airbag, a welded gondola would be placed underneath. With the propeller to generate propulsion, will it be able to move? ”

"Airbags?"

"Sealed airbags? The airbag can't float into the air. ”

"As you said, hot air balloons can rise into the air and rely on a constant injection of heat into them. But with a sealed airbag, you can't breathe fire into it. ”

“……”

"So, we just need to follow this principle," Liu explained. Expand your mind, it doesn't exactly need firepower to support it. That's the experiment I'm going to do. ”

As he spoke, Liu Jinghong opened the valve of the tin can to inflate the balloon, and after a while, the balloon inflated. Liu Jinghong tied the balloon, held it in his hand and said, "Now, this balloon is bulging, which means that it is completely sealed." ”

At this time, Jin Shiteng asked, "And then?" Is it heated externally? ”

Liu Jinghong laughed: "Do you need to heat it?" ”

As he spoke, he let go.

'Whew-' The scene erupted.

But with Liu Jinghong's letting go, the balloon quickly jumped into the sky, constantly rising.

The crowd exclaimed, "Why did it rise into the air on its own?" ”

"What's going on? Why did it go to heaven on its own? ”

"It's not heated this time, why does it have the momentum to rise?"

"What kind of gas are you pouring into?"

“……”

Liu Jinghong smiled and said: "On the basis of this balloon, if a power facility that can move forward is installed, do you think it will become a real flying machine?" ”

Everyone nodded suddenly. That's absolutely true.

If this balloon with lift has power facilities, then it may really be able to become a real flying machine.

Liu Jinghong said: "Electrolysis of water, get hydrogen." Hydrogen is lighter than oxygen, and its density is the smallest gas we find in the world today. This means that as soon as hydrogen is exposed to the air, it will quickly rise into the sky. If one airbag is filled with hydrogen, it will lift the entire airbag into the air. ”

"If you add a cockpit under this hydrogen, increase the power setup. It will become a real flying machine. When it rises to a certain height, we can implement internal decompression and excrete hydrogen. When the buoyancy of hydrogen reaches an equilibrium with gravity, it can no longer rise into the air and levitate at a certain height to move. ”

"That's the airship idea."

“……”

At this point, all the personnel of the Kyushu Academy of Sciences have been displayed.

And the results of the follow-up physicists seem to be no longer important in the eyes of the guests.

Everyone fell into absolute silence......

They had a premonition of an epoch-making new era.

The era of alternating current.

Industrial Age.

The Great Space Age.

It's coming soon. The world's science will have a big bang chemical reaction with the end of the Kyushu Science and Technology Award......

After the physics competition ended, the 1,000 guests looked at the young man sitting on the rostrum and chatting and laughing with Ge Qingping, the young man who was wearing a Mao suit and was thin.

There is some jealousy in my heart, but more respect and worship.

He's alone, and he's about to push the whole world.

PS: There's another chapter later. Wait a minute.
